Efficacy of salpingography and transcervical recanalization in diagnosis, categorization, and treatment of fallopian tube obstruction

The efficacy of selective salpingography (SS) and transcervical recanalization (TCR) in diagnosis, categorization, and determination of optimal treatment modality for fallopian tube obstruction was investigated. Methods: SS and, in some patients, TCR was performed in 430 patients with a diagnosis of obstruction of one or both fallopian tubes, as determined by hy sterosalpingograms (HSG). All patients (age 21-46 years) had an infertility problem for at least 18 months. Results: In 196 patients, 325 tubes were patent on SS. TCR recanalized 243 tubes in 176 patients. Disease of the distal tube was demonstrated in 66 patients. There were 39 live babies in a group of 176 patients with successful TCR. Best live birth rate was in 7 of 12(58%) patients with underlying endometriosis, followed by postsurgical strictures in inflammatory disease, 6 of 31 (19%), and salpingitis isthmica nodosa in 25 of 168 (15%). There were no pregnancies in patients with cobblestone pattern of the distal tubes. Conclusions: SS and TCR were capable of correcting obstruction of the proximal tubes in 243 of 465 tubes in 176 of 234 patients (75%). With patency of the proximal tube restored, the distal tube could be assessed for changes indicative of damage to the ciliated epithelium which was likely to reduce the ability to become pregnant. This allowed for the triage of patients into groups benefiting from the relatively inexpensive and low complication TCR or patients in need of in vitro fertilization or similar assisted reproductive technologies.
